liability for consequences of misuse by the operator� Improper installation and
use of the devices results in a loss of the warranty claims�
• For medium temperatures above 50 °C some parts of the housing can heat up
to over 65 °C� Moreover, during installation or in case of a fault (e�g� housing
damage) media under high pressure or hot media can leak from the system� To
avoid personal injury, take the following measures:
► Install the unit according to the applicable rules and regulations�
► Ensure that the system is free of pressure during installation�
► Protect the housing against contact with flammable substances and
unintentional contact� To do so, equip the unit with suitable protection (e�g�
protective cover)�
► Do not press the pushbuttons manually; instead use another object (e�g�
ballpoint pen)�
